I've been pulling my hair out trying to finalize testing on an Android app that will not release data from the previously installed version. I'm using a Nexus 7 and Samsung Galaxy, and no matter what I do — clear the app cache, clear the app data, force quit the app, uninstall the app — it continues to load the new version with the old problems in place, and I know they've been corrected. The way I know this is that I did a complete wipe and factory reset of the Nexus, used a new Gmail account specifically for this experiment, and the app loaded as it should. But once I go back and try my admin Gmail account, it goes back to loading old data again.
Is there a way to COMPLETELY delete old data, so that each test of the APK is as if it was by a first time user? The Beta Test area I'm using in Google Play is no help.
Thanks.
